Soon after the exploit, the attacker left an on-chain message saying, \u201cOk, funds will be returned later,\u201d which was flagged by blockchain security firm PeckShield.<\/p>\n

Less than an hour later, the attacker began sending stolen crypto back to GMX, signaling they had accepted the white hat bounty offered by the team.<\/p>\n

What Happened After the Attack?<\/h2>\n

Shortly after the July 9 attack on GMX, the exchange announced on X that it was offering a $5 million bounty, which is roughly 12.5 percent of the stolen amount, if the attacker returned the funds.<\/p>\n

GMX also said the incident would be treated as a white hat hack and the attacker could keep the bounty without facing any legal consequences.<\/p>\n

The team also mentioned they were prepared to provide proof of source of funds if the attacker needed it to use the bounty. They gave the attacker a 48-hour window to return the funds before initiating legal proceedings.<\/p>\n

The crypto exchange announced that the attacker could retain 10% of the stolen funds as a white hat bounty reward, provided that 90% of the crypto was returned to the designated addresses.<\/p>\n

This type of exploit is common among platforms in the crypto space. Hackers often manipulate oracles or internal data to artificially deflate a token\u2019s value, allowing them to drain assets by swapping at distorted prices.<\/p>\n

A few weeks ago, Resupply.Fi was a victim to this, losing $9.6 million to the exploitation. The attacker distorted the value of crvUSD, collapsing its exchange rate against reUSD to zero. This manipulation made it possible to borrow assets nearly free of charge.<\/p>\n
